16 TRICHOPTERA. 



The position of the insect is doubtful. It is not a true 

 Anaholia as restricted to A. nervosa and allies, nor will it 

 come very satisfactorily in either Stenophylax or the De^- 

 ■molauUus group of Lrnmophilus. On the 29th July, 

 Mr. Stainton took nineteen examples from off stone posts 

 bordering the road between Pontresina and Samaden, in 

 the forenoon, and in the evening twenty-six more from ofi" 

 the same posts, yet he did not notice, either then or at ot'ner 

 times, a single specimen on the wing; on the 2nd August 

 an additional nineteen ; and on the 30th July, three dead 

 ones floating on tlie water of a little tarn above the Lago 

 del Croce, in the Bernina Pass. These latter are much 

 smaller than the others, but yet larger than British spe- 

 cimens. 



Hydroptila tineoides, Dalm. Two examples, in tlie 

 evening of July 23rd, at the Lake of Sils. 



Odontoceras albicornis, Scop. Six on the 25th July, at 

 the south-east side of the Lake of Sils; sitting on grasses in 

 the day-time. 



My.stacldes nigra, L. Forty-nine examples on the 23rd 

 and 24th July, at the Lake of Sils, chiefly by sweeping 

 ruslies ; a few were sitting on stones. 



Cyrmis tr'imaculatiis, Curt. Two examples from the 

 Lake of Sils, on the 23rd July. 



At Ziirich, from the 5th to 7th August, were found Lej)- 

 focerus cinereus, Curt., the brown form; L. albifrons, L., 

 and one male of i. aureus, Pict.,a species I did not possess, 

 and which appears to be rare, for I have only seen single 

 specimens from Sweden, Holland, and Switzerland; Setodcs 

 lacusiris, Pict. ; Cyrnus trimaculatus, Curt.; NeurecHpsis 

 himaculata, L., in extreme abundance, recalling to mind one 

 of its synonyms, tigurinensis, Fab.; Hydroptila angustella, 

 JiI'Lacli.; PsycJiomyia (jracHipes, Curt.; P. fray ills, Pict.;
